Preeclampsia Reduction by Exercise Project

Women who are 18 to 40 years of age, between 12 and 20 weeks pregnant, and who have had preeclampsia in an earlier pregnancy may be eligible for this study. The Preeclampsia Reduction by Exercise Project (PREP) is investigating the possibility that women who had preeclampsia in a previous pregnancy might be able to reduce the risk of developing preeclampsia in the current pregnancy by initiating a regular walking exercise program.
